  </build>
</project>

1.2配置數據源（由於是在ssh框架下因此數據源和hibernate用的同樣在sping-Hibernate下，數據源但是dbcp、c3po根據需求本身配置i）web

<!--配置數據源-->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
        <property name="driverClass" value="${jdbc.driver}" />  <!--數據庫鏈接驅動-->
        <property name="jdbcUrl" value="${jdbc.url}" />     <!--數據庫地址-->
        <property name="user" value="${jdbc.username}" />   <!--用戶名-->
        <property name="password" value="${jdbc.password}" />   <!--密碼-->
        <property name="maxPoolSize" value="40" />      <!--最大鏈接數-->
        <property name="minPoolSize" value="1" />       <!--最小鏈接數-->
        <property name="initialPoolSize" value="10" />      <!--初始化鏈接池內的數據庫鏈接-->
        <property name="maxIdleTime" value="20" />  <!--最大空閒時間-->
    </bean>

1.3建立spring-actitvit.xml文件spring

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="
              http://www.springframework.org/schema/context
                http://www.springframework.org/schema/context/spring-context.xsd
            http://www.springframework.org/schema/beans
            http://www.springframework.org/schema/beans/spring-beans.xsd

            http://www.springframework.org/schema/tx
            http://www.springframework.org/schema/tx/spring-tx.xsd">

    <!--********************************************配置activiti***************************************-->

    <context:component-scan
            base-package="org.activiti.editor">
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>




    <!-- 單例json對象 -->
    <bean id="objectMapper" class="com.fasterxml.jackson.databind.ObjectMapper"/>



    <!-- activiti的processEngine配置 -->
    <bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration">
        <property name="dataSource"><ref bean="dataSource"/></property>
        <property name="transactionManager"><ref bean="transactionManager"/></property>
        <property name="databaseType" value="mysql"></property>

        <!-- 沒有表建立表 -->
        <property name="databaseSchemaUpdate" value="true"/>
        <!-- 是否激活Activiti的任務調度 -->
        <property name="jobExecutorActivate" value="false"/>
        <property name="processDefinitionCacheLimit" value="10"/>
        <!-- 生成流程圖的字體 -->
        <property name="activityFontName" value="宋體"/>
        <property name="labelFontName" value="宋體"/>
    </bean>


    <!-- 加載activiti引擎processEngine -->
    <bean id="processEngine" class="org.activiti.spring.ProcessEngineFactoryBean">
        <property name="processEngineConfiguration" ref="processEngineConfiguration"></property>
    </bean>

    <!-- 7種服務 不必定所有使用 -->
    <bean id="repositoryService" factory-bean="processEngine" factory-method="getRepositoryService"/>
    <bean id="runtimeService" factory-bean="processEngine" factory-method="getRuntimeService"/>
    <bean id="formService" factory-bean="processEngine" factory-method="getFormService"/>
    <bean id="identityService" factory-bean="processEngine" factory-method="getIdentityService"/>
    <bean id="taskService" factory-bean="processEngine" factory-method="getTaskService"/>
    <bean id="historyService" factory-bean="processEngine" factory-method="getHistoryService"/>
    <bean id="managementService" factory-bean="processEngine" factory-method="getManagementService"/>





</beans>

<property name="dataSource"><ref bean="dataSource"/></property> 即引用在hibernate中配置的數據源sql

1.4將配置彙總寫進applicationContext上下文中數據庫

集成完成啓動服務後會自動建立表幾個服務也都交給spring去管理了express
